Options outlook web app version

The light version of Outlook Web App is designed for use with older web browsers that aren't supported by the standard version of Outlook Web App, for use over slow connections, and to meet accessibility needs by providing a simplified interface that's easier to use with screen readers.

The light version of Outlook Web App has fewer features than the standard version of Outlook Web App. For example, there are no separate controls to change the size of fonts. Instead, see the Windows accessibility website. This includes links to accessibility options for your operating system. For example, you can make everything on your screen bigger, increase the contrast, use the built-in narrator to read you what's on the screen, and more. For more information about different options in each version, see Compare the standard and light versions of Outlook Web App. For information about supported browsers, see Supported browsers for Outlook Web App.

Note: If you're wondering why you're seeing the light version of Outlook Web App, how to get back to the standard version of Outlook Web App, or how to use a different email program on a mobile device or computer, see Outlook Web App Light.
